About to buy some new plugs,dont have NGK`s in at the minute, so not sure on which ones to get ?

Its a 95 WRX with no real engine mods,just exhaust/bigger TMIC and panel filter,so which NGK to go for ??

cheers

 

pfr6b gapped to .65mm-.7mm

 

cheers,i see those plugs come as 0.8 as standard,is 0.65/0.7 better ?

cheers again

 

No idea sorry just my garage always gapped them to 0.7mm and looked on here for gap size.

 

0.7 will be fine for a standrad car it just stop the spark from blowing under boost i gap mine to 0.6 but im running a 20g at 1.6 bar of boost and use pfr7b but ythe 6 will be fine for yours
